Brief Summary
This randomized controlled clinical trial (RCT) aims to evaluate the adjunctive efficacy of two domiciliary treatments in patients with periodontitis undergoing non-surgical periodontal therapy. After signing the informed consent, patients satisfying the inclusion criteria will undergo professional supragingival and subgingival periodontal debridement of both arches performed using ultrasonic instrumentation, manual instrumentation with Gracey curettes, and air polishing with glycine powder. After the initial treatment, participants will be randomly allocated into two groups according to the assigned domiciliary therapy:
- Aftoral® Oral Gel containing hyaluronic acid, xylitol, and glycerophosphoinositol, applied domiciliary for 15 days.
- Unidea® chlorhexidine digluconate mouthwash 0.20%, used as a domiciliary rinse for 15 days. The total duration of the study will be 6 months. Patients will be evaluated at the following time points: Baseline (T0); 1 month after baseline (T1); 3 months after baseline (T2); 6 months after baseline (T3). Professional oral hygiene procedures will be repeated at T2 and T3. At each visit, a patient satisfaction questionnaire regarding the assigned product (taste, smell, consistency, persistence, and ease of application) will be collected. In addition, the following periodontal clinical parameters will be recorded using a periodontal probe at each site:
- Gingival Recession (GR)
- Probing Pocket Depth (PPD)
- Bleeding on Probing (BoP)
- Clinical Attachment Level (CAL)
- Plaque Control Record (PCR)
- Tooth Mobility (TM)

Outcome Measures
Primary Outcomes (5)
Change in Probing Pocket Depth (PPD)
Evaluation (in mm) of the depth of the gingival sulcus, through a millimeter periodontal probe; it is detected from the gingival margin to the bottom of the gingival sulcus or periodontal pocket, evaluated at 6 sites.
Baseline (T0), after 1 (T1), 3 (T2) and 6 months (T3)
Gingival Recession (R)
Evaluation (in mm) of the displacement of marginal tissue, through a millimeter periodontal probe; it is detected from the cemento-enamel junction (CEJ) to the gingival margin.
Baseline (T0), after 1 (T1), 3 (T2) and 6 months (T3)
Change in Bleeding on Probing (BOP%)
Quantitative assessment (percentage) of the bleeding sites (6 per tooth in total). Formula = n ° bleeding sites / n ° probed sites x100
Baseline (T0), after 1 (T1), 3 (T2) and 6 months (T3)
Change in Clinical Attachment Level (CAL)
Evaluation (in mm) of the distance of the cemento-enamel junction (CEJ) to the bottom of the gingival sulcus or periodontal pocket, evaluated in 6 sites.
Baseline (T0), after 1 (T1), 3 (T2) and 6 months (T3)
Change in Plaque Control Record (PCR%)
Evaluation of the presence of plaque on the 4 surfaces of teeth on the total amount of dental surfaces. Formula = n ° sites with plaque / total n ° of dental surfaces x100
Baseline (T0), after 1 (T1), 3 (T2) and 6 months (T3)

Trial Group
EXPERIMENTALHome treatment with hyaluronic acid.
Control Group
ACTIVE COMPARATORHome treatment with chlorhexidine.
Interventions
Patients will use Aftoral® Oral Gel solution for the domiciliary application once a day for 15 days after the visits (no rinsing and eating for 30 minutes after gel solution application).
Patients will use chlorhexidine mouthwash 0,20% for the domiciliary application once a day for 15 days after the visits (no rinsing and eating for 30 minutes after mouthwash application).
